Patent DE-3837100-A1 (DE)
Inventor: GLASHEEN WILLIAM MICHAEL
IPC: G02F1/09
Filed: 1988-11-01
Abstract: A Faraday effect optical switch comprises a monolithic substrate on opposite sides of which are polarization rotation layers. A reflection layer overlies one of the rotation layers. A polarizer and an analyzer are arranged side by side on the other of the rotation layers. Radiation is directed onto the switch by an input optical fibre. Radiation reflected from the reflection layer is received by an output optical fibre. The presence of a magnetic field varies the polarization of the radiation and thus the magnitude of the signal derived from the output optical fibre. A flowmeter comprises two such switches. The flowmeter includes a turbine (24) and a swirl generating impeller (25) each having magnets (35,36) mounted on their periphery. Positioned on the exterior of the flowmeter housing in line with the magnets on the turbine and impeller are monolithic Faraday effect optical switches (37,38). Each time the magnets pass by the Faraday switches the switches produce output pulses. The phase difference of the output pulses is an indication of mass flow rate. <IMAGE>

Title: Football boot which is suitable for the sport type
Inventor: KLAUSNITZER HERBERT
IPC: A43B5/02
Filed: 1988-11-04
Abstract: Decisive innovations and improvements are making the conventional football boot into a sports device which is adapted to the sport type. In this football boot as a sports article, which is designated as suitable for the sport type, the boot surface is provided with a ball-contact material with a greater coefficient of friction than previously or consists of this material. Extensively plane surfaces in the toe, heel and side region with underlaid filling, springing or damping material as well as the avoidance of interfering contours in the lace region by means of an overlaid tab in the same construction make possible a qualitatively better football game which is richer in variants as a result of better ball guidance, optimum ball control and considerable, well-controllable rotation.

Title: Motor-vehicle seat with an approximately U-shaped bar assigned to the seat cushion
Inventor: ANDRES RUDOLF DIPL ING
IPC: B60N2/42
Filed: 1988-12-10
Abstract: The invention relates to a motor-vehicle seat with an approximately U-shaped bar which is assigned to the seat cushion and the free limb ends of which are mounted such that they can move by swivelling about a limb axis lying at the rear, and the web of which, which connects the two limbs, fits close to the front side of the seat cushion and on the underside thereof, the support being brought about by at least one device which locks the bar with respect to the seat frame. In the case of a motor-vehicle seat of this kind, a safeguard against submarining, which safeguard does not present an obstacle during normal travel, is obtained if the bar can be transferred from a lower out-of-operation position, which does not prevent the spring movements of the seat cushion, into an upper operative position by a pyrotechnic driving unit, which forms a component of the lockable device, using the generated propellants.

Patent DE-3901094-A1 (DE)
Title: Motor vehicle broadcast receiver
Inventor: SAITO YOSHINORI
IPC: H04B1/16
Filed: 1989-01-16
Abstract: A motor vehicle broadcast receiver is specified which contains: a first memory for recording received field strength information in accordance with the received field strength determined from a broadcast transmitter currently received when a traffic announcement/programme identification detector circuit outputs a PI signal which identifies a broadcast station sending out traffic programmes or a TA signal which identifies the current sending-out of a traffic announcement; and a second memory for recording received frequency information at the time at which the first memory records the received field strength information. The first and second memory are set up in such a manner that the received field strength information which is recorded in the first memory is compared with a subsequently determined received field strength information in order to overwrite the content of the first memory with the new received field strength information when the latter represents a higher field strength level than the received field strength information previously stored in the first memory. At the same time as the content of the first memory is overwritten, the frequency information contained in the second memory is overwritten with the new frequency information allocated to the higher received field strength so that the broadcast receiver is automatically set to a traffic programme transmitter which generates the highest received field strength at the location of reception.

Title: Electroacoustic plucking musical instrument - is without resonator and has strings of different lengths on triangular support, and tone processor
Inventor: KIEWNING KLAUS
IPC: G10H3/18
Filed: 1989-05-09
Abstract: The plucking musical instrument has a row of strings on a support and are led each over an adjustable strap. The strings are of different lengths as a result of the triangular geometric shape of the support (1). As there is no resonator body, there tone can be amplified by an integrated tone processing system (6-15), using a tone pick-up. The strings are pref secured at one side of the instrument by an incorporated eyelet (2), while at the other end they open into a conventional guitar tuning mechanism. Each string is guided over an adjustable strap (4), dividing it into two differently sounding, usable halves. USE/ADVANTAGE - For country music instruments, with simple mfr and easy playing.

Title: Trimming mass produced flat resistors - by U=shaped laser cutting with optimal side lengths
Inventor: STEFANEK ROBERT DIPL ING
IPC: H01C17/242
Filed: 1989-05-31
Abstract: U-shaped areas (3) are cut which become isolated from the rest of the resistor. A polynomial of degree, n, is used which approximates to the relationship between the length (L) of the sides of the cut (5,6) and the relative resistance change. by reducing this polynomial to a straight line equation, the starting length (10) of the cut required to produce a resistance change (9) is measured. An end length (11) is then produced to raise the degree of the polynomial. With each successive resistor the degree is raised until the n degree is reached. ADVANTAGE - Producing optimal resistance whilst minimising number of measuring and laser adjustment steps.

Title: Compact boring tool or reamer - has eccentric screw to combine radial adjustment and clamping of inserted tool bit
Inventor: FEES HEINER DIPL ING
IPC: B23D77/04
Filed: 1989-06-02
Abstract: Compact design allowing small holes to be machined at high rotational speeds is achieved by using one screw (60) to radially adjust and clamp the inserted toolbit (16,18).  THe screw (60) has an eccentric section (66) and screws into the nut (70) which fits into a recess (44) in the body of the boring bar or reamer. The end of the nut is shaped to accept an adjusting key.  Rotation of the screw (60) causes the eccentric section (66), which bears against the toolbit, to adjust it inwards or outwards.  Clamping is effected by the screwhead (62) clamping onto the toolbit. USE/ADVANTAGE - Compact design with locking feature permitting high rotational speeds.  Can be used for fine boring or reaming.  Can be combined with complex form cutter.

Patent DE-3925137-A1 (DE)
Inventor: HOFFMAN JERZY
IPC: H01F7/16
Filed: 1989-07-28
Abstract: The solenoid actuator comprises a slider 28 including a permanent magnet 36. When the electromagnet 12 is activated, it repels the permanent magnet, thereby moving the slider from its first position as shown towards a second position in which the permanent magnet is attracted to a mass of ferro-magnetic material 38 located adjacent the second position. In a preferred embodiment, the poles of the slider permanent magnet are co-axially aligned with the coil and core 18 of the electromagnet. In an alternative embodiment, the mass of ferro-magnetic material may be eliminated. On de-energisation of the electromagnet the slider returns to its first position. Alternatively the actuator may have a bistable operation by increasing the size of the mass 38 so that it attracts the permanent magnet 36 to latch the slider in its second position when the electromagnet is de-energised. A reed conductor 40 may be attached to the slider for cooperation with contacts 42, 44. <IMAGE>

Gas from the space above the collecting liq. is pumped back to the original cyclone chamber, where its residual liq. content is more completely sepd.  Esp. for dealing with large gas/liq. vols. a number of symmetrical sepn. lines may radiate from a central cyclone unit.  ADVANTAGE - Combined centrifugal and gravitational effects increase total sepn. efficiency.
